No application works for my Beacons

1

Hello. In the Estimote Application the only functionality that is working is (Devices). All others do not work. No beacons is found.
Proximity Demo, Distance Demo, Notify Demo. None!

I am struggling to develop my own application from the documentation and also using the demo applications, but nothing works. Not even the Demo applications!

I use the default UUID since I bought them, I never modified them, and they never worked. B9407F30-F5F8-466E-AFF9-25556B57FE6D.

Anyway. I read everything I could and researched here in the forum for solutions, but I really can not understand what is happening

My Beacons:
Location Beacons OS 4.9.4

My Device. Lenovo L10a40.
Android 6.0

Hi, again. I tested the tests using a Azus Device, running Android 5.0 And it worked correctly.

So now I have the doubt about the Lenovo.
The problem is my device? Operational system? . System version ?.

I have already enabled access to all necessary requirements, Bluetoo and Location.

As I mentioned above, neither Estimote’s application nor self-made applications with the Most recent SDK work!
Can you please help me?
